Magnetic levitation steering mechanism

Abstract

The invention provides a magnetic levitation steering mechanism which is installed between a vehicle body and a steering frame of a magnetic levitation vehicle, and the steering mechanism is an arc movable sliding table, wherein the upper part of the sliding table is connected with the vehicle body, and the lower part of the sliding table is connected with the steering frame; the upper part and the lower part of the sliding table make relative movement with a circular arc movement trail. The arc movable sliding table specifically includes: a roller seat and a rollway body, wherein the rollway body is connected to the vehicle body as an upper part of the sliding table, the roller seat is connected to the steering frame as a lower part of the sliding table; the rollway body is in an arc structure of which an upper flat surface is fixedly connected to the vehicle body and a lower flat surface is in contact with the roller seat, the two moving relatively in a circular arc track. The introduction of the magnetic levitation steering mechanism realizes that a moving point of a steering module forming the steering frame makes arc movement around a relative rest point to drive the vehicle body and the steering frame to make circular arc relative movement together, so that the vehicle passes through a curve track smoothly, and the service life of an air spring and the steering frame is prolonged.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation vehicles, in particular to a magnetic levitation steering mechanism for a magnetic levitation train. Background technique [0002] Maglev train is a train propelled by magnetic levitation force (that is, magnetic attraction or repulsion force). Due to the magnetic force of its track, it is suspended in the air and does not need to touch the ground when walking, so its resistance is only the resistance of the air. The maximum speed of the maglev train can reach more than 500 kilometers per hour. It has high speed, low noise, environmental protection, economy and comfort. Features. [0003] refer to Figure 1-A The schematic diagram of the structure of the magnetic levitation train steering device shown and Figure 1-B shown Figure 1-A The enlarged view of the middle part M and its force schematic diagram. The bogie frame 11 is installed on the track 14, the bogie frame 11 is provide...

AI Technical Summary

Problems solved by technology

To achieve this relative movement (rail, bogie, car body) must solve the following problems: 1) The bogie must fit the track to obtain the maximum suspension force and maintain the direction of motion; 2) The bogie and the car must maintain a certain relative Positional relationship to prevent unbalanced load; 3) The bogie needs to drive the car body to deflect and change the direction of motion, so there must be a connection point between the bogie and the car body, and this connection cannot limit the freedom of the bogie to run along the track

[0014] 1. When the train passes the curved track, the two displacements produced by the air spring must be compensated, and the trajectory is not the real trajectory of the end, which is prone to additional vibration;

[0015] 2. Generate additional force, affecting the flexibility of bogie rotation;

[0016] 3. Lead to complex mechanism, increase manufacturing and maintenance costs
